Step-by-step explanation:

use (a+b/2)h

or use google lol

(5+7/2)6 - numbers in formula

(12/2)6 - parentheses

(6)6 - parentheses

36 - multiply

hope that helped

Given that the diameter of Circle A is 6 cm , and the radius of Circle B is 18 cm , what can be concluded about the two circles?

ELEN [110]

Answer:

The radius of circle B is 6 times greater than the radius of circle A

The area of circle B is 36 times greater than the area of circle A

Step-by-step explanation:

we have

<em>Circle A</em>

$D=6\ cm$

The radius of circle A is

$r=6/2=3\ cm$ -----> the radius is half the diameter

<em>Circle B</em>

$r=18\ cm$

Compare the radius of both circles

$3\ cm< 18\ cm$

$18=6(3)$

The radius of circle B is six times greater than the radius of circle A

Remember that , if two figures are similar, then the ratio of its areas is equal to the scale factor squared

All circles are similar

In this problem the scale factor is 6

$6^{2}=36$

therefore

The area of circle B is 36 times greater than the area of circle A

What’s the simplified form of the expression (T^4/10y^4)^-4

monitta

$\bf ~~~~~~~~~~~~\textit{negative exponents}
\\\\
a^{-n} \implies \cfrac{1}{a^n}
\qquad \qquad
\cfrac{1}{a^n}\implies a^{-n}
\qquad \qquad 
a^n\implies \cfrac{1}{a^{-n}}
\\\\
-------------------------------\\\\
\left( \cfrac{t^4}{10y^4} \right)^{-4}\implies \left( \cfrac{10y^4}{t^4} \right)^{4}\impliedby \textit{then we distribute the exponent}
\\\\\\
\left( \cfrac{10^4y^{4\cdot 4}}{t^{4\cdot 4}} \right)\implies \cfrac{10000y^{16}}{t^{16}}$
